Reaction Steps

Sodium triacetoxyborohydride (1.8 g, 8.4 mmol) is added to a solution of 4-hydroxy-3-nitro-benzaldehyde (1.3 g, 8.0 mmol) and 1-(4-methyl-phenyl)-piperazine (2.8 g, 16.1 mmol) in 50 mL of THF at room temperature, and the mixture is stirred overnight. The reaction is quenched by pouring into 400 mL of water, and the precipitate which forms is collected by filtration. Yield=1.7 g (33%) of 4-[4-(methylphenyl)-piperazin-1-ylmethyl]-2-nitro-phenol oil.
